Sps bleaching a bit...

[JammyBirch]

high temps is what I think the cause is...nitrates are a little high but the temp was ~85.5*F...

So annoying, lost my green slimmer and blue bottle brush...they were rough to start with but now my new red planet and a green deep water, my favorites, have white tips...

Can I just water change, nitrate removal, and add a fan to the sump for cooling? These corals with some damage can I just leave them alone or do I have to clip them?

Leave any stressed corals alone. Snip them if they are RTNing. If you think it's high temp don't do waterchange yet. Let things balance out temp wise then do a waterchange A fan would help w temp but a chiller may be necessary depending how hot you will get

Not sure what RTN is but the tips of three corals are white and look like the skin is coming off. RTN=Rapid Tissue ? Maybe that but in very small areas. The green deep water has that going on, on the encrusted part of the rock.

I guess I'll watch them tomorrow if it gets worse bone cutter time...

Do corals ever come back from tissue loss?

RTN = rapid tissue necrosis
STN = slow tissue necrosis

Slow can sometimes be stopped by fragging or super gluing a dead area. The point of the post above is to avoid doing anything else rapidly because sometimes the cure is worse than the original problem. Let temps drop, use a fan to help cool the water, make sure all your params are good and stable, hope for the best. No rapid changes.

Water has been stable for a day we finally got normal May weather, so i did a 20%water change last night.

Pre-change parameters:
Calcium 410
Alkalinity 8.3
Magnesium 1320
Nitrate 10
SG 1.024

I checked the alkalinity and SG this morning
Alkalinity 8.5
SG 1.024

Everything looks the same, but that's good no more loss of tissue, we'll see how things make out today in the light.

I bumped the alkalinity a little bit today just because i like it better at 9Dkh, it's up to 8.7... Tonight i'll run all parameter tests and see where the numbers are and make my usual bumps.

I hope you don't consider this a major change, the nitrates were too high for my tastes and the other corals are at risk as well so a water change was at hand.
